Think about plotting points in the complex plane to represent the following numbers: -3+8i

4i

6

5-2i

A coordinate plane is labeled quadrant 1 in the uppercase-right quadrant, quadrant 2 in the uppercase-left quadrant, quadrant 3 in the bottom left quadrant, and quadrant 4 in the bottom right quadrant.
Where is each point located on the graph?
–3 + 8i is
on the horizontal axis
.

4i is
on the horizontal axis
.

6 is
.

5 – 2i is
.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

answer: #1 ads up by 8 and i don't know #2

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
